FRANKLIN HARDINGE, OTE' CHICAGO, ILLINOIS, ASSIGNOR TO HARDINGE BROS., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

WATCHMANS CLOCK.

To all whom it may concern:

Be it known that I, FRANKLIN HARDINGE, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented a certain new and useful Improvement in VVatchmens Clocks, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to an improved watchmans clock construction and devices used in connection with same.

My invention relates to that form of watchmans clocks in which a paper record employed for the purpose of recording the work of a watchman recurring intervals. The paper is preferably advanced by clockwork and at the intervals mentioned a record is made upon the paper by means of a suitable key. The key employed in this connection consists of two jaw members pivoted to the body of the key and normally held apart sothat they may .not be brought together, by means of a suitable lock. The jaw members have secured to them, lever members extending to the rear of the pivotof such jaw members and a single spring construction is employed to hold the lock in place and to also move the levers from their position against the record to their open position.

A further essential feature of my invention consists in providing in the casing of the key an alarm mechanism to indicate that the key has been properly operated.

My invention is applicable particularly to that form of watchmans clock adapted to be carried around by the watchman, the keys usable with such clock being secured at the different stations required to be visited by the watchman.

The several drawings illustrating my invention are as follows:

Figure 1 is a diagrammatic face View of a portion of the watchmans clock showing in section the key guides employed to receive the watchmans key. In this ligure there is also shown a key in place in the clock, the framework of the key being shown in section. Fig, 2 is a sectional view of the key taken along the line 2 2 of Fig. 1. Fig. is a view similar to that shown in Fig. 2 in which the key is in its operative position and is shown in place in the clock mecha- Specification of Letters Patent,

y?, nism. Fig. 4c. is an enlarged view sinfil'ir't` that shown in Fig. 1 of a portion of the key mechanism. Fig. 5 is a sectional view of the parts shown in Fig. A, taken along the line 2 2, in Fig. 1. Fig. 6 shows an enlarged detail view similar to Fig. 5, of the locking mechanism provided to normally preventI operation of the recording devices carried by the key.

Similar numerals refer to similar parts throughout the several views.

As shown in the drawings, 1 is the clock casing in which 2 is a disk of suitable material, as paper, adapted to receive the impressions made by the watchmens key, and to be suitably driven by means of clockwork contained within theclock case 1. rlfhe clock here shown is of a type adapted to be carried around during his work by the watchman. The casing of the clock has secured thereto at 3 an outer key guide, while registering therewith an inner key guide 4t is correspondingly located. The guides 3 and 4- are adapted to receive the casing 5 of the key which in the drawings is shown as a square tube. Within the tube 5, a second tube 6 of similar format-ion is adapted to slide.

As indicated in Fig. 2, the left hand end of the tube 6 is slotted and has mounted therein the two jaws 7 and 8 pivoted to the tube 6 at 9, these jaws being normally held apart by the spring 10. The outer ends of the aws 7 and 8 have formed thereon suit able dies 11 adapted when brought together to form a characteristic impression upon the record disk 2. A lock 12 mounted in the tube 6 so as to slide upon the pivot 9 is provided normally to prevent the jaws 7 and 8 being brought together. The spring 10 is slotted at its left hand end, as indicated in Figs. 1 and 4t, so as to engage both the jaws 7 and 8 and the lock 12 in such a manner that either the aws 7 and 8 or the lock 12 may be moved against the action of the spring as desired without operating those portions of the spring engaging the other members. Levers 13 and 14e are loosely secured to the jaws 7 and 8 by means of rivets 15 and 16 and so conformed. as to have fulcrums at 17 and 18 bearing upon the inside of the tube 6, the right hand end of such levers being extended to the right of the pivot 9 so as to be engaged on their outer surfaces by portions of the spring 10. A cam 19 is sup- CII ported by the rods Q0, 20, from the tube 5 in such a manner that when the tube 6 is moved in the tube 5, the point of the cam enters between the right hand ends of the levers 13 and 1-l and thereby moves the let't hand end ot such levers together, thus bringing the jaivs 7 and S together if the lock 12 is so moved as to permit this motion. A spring Q1 is provided extending between the post 22 carried by the tube 5 and the post 23 carried by the tube (l, the function of this spring being' to normally maintain the tube (5 in outer position relatively to the tube 5. rille posts Q0, 20, and are contained in a slot formed in the side ivalls ot' the tube C, so that such may be moved relatively to the tube 5.

Fig. G shoivs, in a vieiv similar to Fig. 5, the relation ot the lock 12 relatively to the inner ends ot the jaw members 7 and S, by vvhich operation ot such javv members is prevented unless the lock is removed from .betvveen them. This tigure also illustrates the nature ot the connection between the jaiv members 'i' and 8 and the actuating leversI 13 and 1st, which, as described above, is a' loose` connection to permitthe engagement ot the janv members 7 and 8 at the outer ends of the levers 123 and la rather than at the points ot' connection of such levers to the jaw members.

As shoivn in Figs.' 1 and e one ot' the rods 2O is extended outside ot the tube 6 and carries a roller Q5 adapted to engage the slot Q6 formed in the outer key guide 3. By this means the insertion of the key in any but the right position in the key guide 3 is prevented. One ot the Walls of the tube G is extended as indicated at 27 and adapted to engage a spring QS carried Within the right hand end ot the tube 5. The tree end of this spring QS, by its engagement With the right hand end of the projection 27, is adapted to be snapped into engagement with the upturned projection 29 on the portion 27 When the tube is moved into the tube 5. The sound produced by the spring striking the projection 9.9 is an indication to the Watchman that the key has been properly operated. Shutters 30, 30, are provided at the inner end ot' the key guide 3, such shutters being pivoted at 31j 31, and engaged by the plunge-rs 33, as a result of the operation ot the springs 3Q, 32, such shutters serving to close the opening formed in the key guide 3 when the key is Withdrawn from such guide.

llien the key is inserted in the key guide 3, the jaivs 7 and 8 pass one above the other below the disk 2, and the lock 12 comes into engagement With a bar 3st disposed across the outer end ot the guide 4t, in such a position as to engage the lock and move it to tne right against the action of that portion of the spring 10 engaging such lock. Vith the lock thus out of position it is possible to move the levers 13 and 14 and thus the jaws 7 and 8 by the action oi the cam 19 Which is pushed between the right hand end of the levers 13 and 141 when the tube 5 is pushed inivard against the tube 6. rlhis motion is continued until the spring by slipping from the end Q7 ot the tube and into engagement with the upturned projection 29 gives an indication that the cam 19 has been moved sutiiciently bet-i. veen the right hand ends ot the levers 13 and 14s to properly operate the dies 11 to make an impression upon the record Q. As a result ot the relation ot the levers 13 and 1st to the jaws 7 and S it ivill be observed that the pressure exerted upon the inner end of the levers by the Wedge 19 is communicated directly to the lett hand ends ot the levers 13 and 1-1 and thus to the javvs 7 and S in an effective and eiiicient manner without undue springing of the parts.

Thilo I have shown my invention in the particular embodin'ients herein described, I ivish to have it understood, however, that similar constructions may be employed without departing' from the spirit of my invention.
